(at around 55 mins) When Fache visits Andre Vernet in the hospital, he calls him Vernet Andre at the beginning of his interrogation - putting his last name first. Then he doesn't speak his name again. The English subtitles has Fache start into his interrogation using Andre Vernet's name (used correctly this time) later on in the discussion - not at the beginning.

Boom mic visible

(at around 1h 45 mins) When Silas shoots the Bishop, there is a shot from behind Silas where he bends down. You can see the shape of the mike battery pack under just above the rope tied around his waist to help support his robes.

Character error

(at around 1h 4 mins) Leonardo Da Vinci's The Last Supper is referred to as a fresco. Leonardo painted The Last Supper on DRY and not wet plaster, so it is not a true fresco. Because a fresco cannot be modified as the artist works, Leonardo instead chose to seal the stone wall with a layer of pitch, gesso and mastic, then paint onto it with tempera. Because it is not a true fresco, it cannot be moved easily, and this fact has caused it much deterioration and damages over the years. Furthermore, as it has received so much restoration, it is impossible to read as much into the detail of the painting as the narrative implies, as the level of detail concerned is more restoration than Da Vinci's original.

(at around 1h 7 mins) Sir Leigh Teabing refers to the phenomenon of peoples' minds interpreting the same thing differently ("seeing what it wants to see") as scotoma. In reality, it's called pareidolia. Scotoma is the natural "blind spot" inherent the eyes of most mammals with good vision.

(at around 1h 2 mins) When Teabing explained the situation of Rome at the time of Emperor Constantine to Sophie, he mentioned that "Three centuries earlier, a young Jew name Jesus had come along, preaching love and a single God." This statement is false, Jesus did not preach a single God. Jesus did his ministry only among the Jews in Israel, who already believe in a single God. It was Jesus' apostles, Peter and Paul, who later came to Rome and preached Jesus' gospel and a single God to the Romans who still worshiped many gods.

(at around 1h 3 mins) Teabing says that Jesus Christ was regarded as a human prophet until Constantine's party narrowly voted to deify Jesus in 323. In fact, Jesus Christ had been regarded as God in human form in most Christian documents since AD 95 and possibly early as AD 40. Around 300 a "heresy" was proposed to downgrade Jesus to a mere human prophet, but this new idea was voted down in a landslide in 323 in favor of the original concept of Jesus as God. This council was simply telling everyone what most already believed.

(at around 1h 55 mins) Langdon deduces that the orb that ought be on Newton's tomb; the orb with rosy flesh that fell from the heavens and inspired his life's work is A-P-P-L-E. But Newton's identification of gravity was based on his observation and study of a C-O-M-E-T. An apple was not involved, and his life's work was primarily mathematics.

(at around 35 mins) When Langdon tells Sophie about The Holy Grail, he says the story started "more than a thousand years ago", with a crusade that was started to capture Jerusalem. The crusade he is referring to, was commanded by Godfroi Du Bouillion in 1099, so it won't be "more than a thousand years ago" until the year 2100.

(at around 1h 2 mins) Teabing says that in 325 AD Constantine "unified Rome under a single religion: Christianity". This statement is false. Constantine granted numerous privileges to the Christians, but it was not until 380, under the rule of the emperor Theodosius I, that Christianity became the official religion.

Langdon and others continually refer to 'Leonardo da Vinci' as "Da Vinci". However, "da Vinci" refers to his city of origin, and is not technically a surname. Historians and art aficionados always refer to him as Leonardo.

Continuity

When Sophie is being held at knife-point by Silas, you see blood trickling from the cut the knife point makes. When the scene shifts back, there is no blood or cut. When it shifts again, the cut and blood are back, and she has the cut/healing wound for the rest of the film.

(at around 2h) When Robert and Sophie are in the depths of Roslyn Chapel they lift a carpet to reveal a trap door. As they lift the carpet the fleur-de-lis is clearly visible, in the next scene it is obscured by debris and needs to be cleaned out to be recognizable.

When they are on Teabing's plane, Sophie goes back to Silas to question him. She rips the duct tape off his mouth. Then Langdon gets her to walk away. Later, Sophie, Langdon, and Teabing are talking at the front of the plane, and Silas can be seen in the background, with the duct tape back on. Neither Sophie nor Langdon had replaced the duct tape prior to leaving Silas.

(at around 2h 10 mins) As Langdon and Sophie walk away from the Roselyn chapel in discussion there is a distinctive 1960s light blue Morris Minor Traveller and another small car in the background. The cars then change to a black Range Rover Discovery and Rover 75 in the next take from roughly the same point. A few moments later a wide shot of the church shows just two cars in the grounds.

When Fache shows Langdon the hidden writings with the UV lamp, there are only the Fibonacci's suite and the Latin quote. Later in the bathroom, Sophie Neveu tells him Fache erased the last line which was "P.S. find Robert Langdon" and shows him a picture with the complete message.
Later, when they both come back to the murder's scene, Neveu and Langdon are trying to decipher the hidden message using the UV lamp. For a short moment, over Langdon's shoulder we are able to see the line Fache has supposedly erased.

(at around 53 mins) When Robert and Sophie jump into the armored vehicle and drive off the rear doors are open. The camera shows Vernet on the ground watching the van drive off with the doors now closed.

(at around 1h 30 mins) When the plane is taxiing on the ground in England, from the view in the cockpit it is clear that the taxiway ahead dead ends in a field with woods to the right. From the outside view the plane is shown going straight through the intersection past the signalman, then turning right into a hangar.

(at around 1h 50 mins) When Teabing is pointing his gun at Sophie and he wants her to open the cryptex, we see a close up of Robert Langdon who says "one moment". He has his left hand raised. In the next shot, when we see Langdon and Teabing, Langdon's hands are down.

When the police confront Silas, he shoots a couple of them and then the priest rounds the corner and Silas, thinking that it's another police officer, shoots him. A moment later, several officers confront him and he raises the hand holding the gun. The slide is locked back as if the last round had been fired. There's a cut that shows the officers with their guns pointed at Silas but, when camera shifts back to him, the slide is forward and he's then shot by the officers.

(at around 10 mins) As Langdon enters the elevator located in the Louvre on the way to the site of Sauniere's murder, the top button on his shirt is buttoned. When he exits the elevator, the button is undone.

Crew or equipment visible

(at around 50 mins) As Robert and Sophie travel in the back of the armored van to Leigh Teabing's residence, they hold hands in an attempt to calm Robert due to his claustrophobia. As they hold hands, an intermittent yellow light from an external source (supposedly street lamps) is seen. It would be impossible to see any such light from within the back of an armored van. It has also been revealed that they are traveling along a secluded country track with no street lighting.

Errors in geography

Sophie presses the tracking device he's found in his pocket into a (white) bar of soap he's taken from the toilets and throws it out of the window into the back of a truck. The Louvre toilets are supplied with large lemon-shaped (and lemon-scented... and lemon-colored) soaps fixed to metal rods over the sinks. The Louvre toilets do not have windows at all.

Factual errors

Vinegar or scientifically known as acetic acid is a weak acid and thus unable to dissolve a sturdy material such as papyrus. Even a strong acid, like hydrochloride acid, will takes hours to dissolve papyrus. So actually they can just force open the cryptex and the vinegar-soaked papyrus would still be intact and readable.

(at around 12 mins) When flying in the private jet and taking a call from Silas, the Bishop Aringarosa is using a cellular (GSM) phone. At this height, confirmed by a shot through the window revealing the clouds canopy below, it is impossible to get mobile network coverage.

(at around 1h 12 mins) Teabing says that knowledge that Christ was human would bring down the Church by proving that "the greatest story ever told is a lie." However the Church has always held that Christ is simultaneously fully human and fully divine. Further, the Bible nowhere says that Christ was not married, it only doesn't say that he was. Although extremely unlikely after 2,000 years, if it were discovered that Christ had married and had children it wouldn't have any effect on the Faith.

As Teabing, Langdon, and Sophie are arriving at the airport in England, several English police vehicles are shown on their way to intercept them. The sirens sounding on the police cars are those of American police vehicles. English police sirens sound much different than American ones.

As the plane is arriving at the airport in England, Sophie looks out the airplane window and sees several police vehicles on their way to intercept them. However, her view from the window is following the vehicles as if the airplane is moving sideways.

The bottle of 1976 wine offered to Manuel Aringarosa (Alftred Molina) reads Bordeaux Supérieure at the top, but with the Languedoc appellation of origin. Bordeaux is at the south-west of France and Languedoc is at the south-east. Furthermore, Languedoc was not recognized as an AOC until 1975, after which it was allowed to be displayed on labels as Coteaux du Languedoc, never as Languedoc generically.

Miscellaneous

At the beginning of the movie Robert is on a conference about symbols. The first pictures he shows to the audience is a hood that the audience interprets as "racism", "hatred" or "Ku Klux Klan" but Robert says they would disagree in Spain where there are robes worn by priests. No priests dress that way in Spain, those are called "nazarenos" (nazarenes) and are laypersons who dress like that in the street processions.

Incorrectly regarded as goofs

(at around 49 mins) The cryptex was said to be made by Leonardo Da Vinci, and the clue to open it refers to Isaac Newton's grave. Da Vinci (1452-1519) died 124 years before Newton (1643-1727) was even born. However, Sophie says that the cryptex was only designed by Da Vinci, not made by him. In the novel, Sophie states that this cryptex was built by her grandfather.

(at around 4 mins) In Langdon's opening presentation on symbology, he shows a series of slides of modern symbols and their ancient origins. The CND "peace sign" logo is shown followed by an inverted crucifix. In fact the CND logo was created in the 1950s in Britain, by superimposing the two semaphore symbols for "N" and "D", to stand for "nuclear disarmament". The false "broken cross" history of the symbol was invented in the 1970s in the United States - suggesting Langdon didn't do his research properly. However, Langdon's presentation doesn't just speak of the intended meaning of symbols, but also of the (often presumptuous) interpretation of them, making the CND slide particularly relevant.

(at around 1h 1 min) Teabing says that Constantine converted to Christianity on his deathbed. While it is true that Constantine became a follower of Christianity much earlier, it wasn't until he knew he was dying that he was baptized by the Arian priest Usebius. This was in accordance with the custom that a person was not baptized until old age in order to absolve them from as many sins as possible. Constantine died a few days after his baptism. This would technically make Teabing's remark true by today's standards, which call for converts to be baptized into the church. In today's world, Constantine was not a true Christian until he was baptized.

Plot holes

There was no need to know the capsule's combination in order to open it as vinegar is easily frozen in a household freezer. Simply freeze the capsule and then smash it open to reveal the internal message.

The cut of the initial sequence of the movie (intercuts between the Louvre murder and Langdon's lecture), as well as the fact that the police officers come for Langdon during his post-lecture signing of books, create a major continuity lapse in the police' reasoning that Langdon is suspect. How could he commit a murder in Louvre (which can be easily timed due to the victim activating the alarm) while giving a lecture to thousand people? (In the book, he is visited by police several hours after the lecture, which would then allow him enough time to possibly commit the crime, as he is suspected.)

If Sophie's grandfather Jacques knew that the holy grail is safely kept at Louvre and no one except Sophie's grandmother (who even Sophie or the Teacher didn't know about, the Teacher even didn't know Sophie was Jacques' granddaughter) knew about it, why did he ask Sophie to find Langdon? If he wanted Sophie to know about her lineage and/or holy grail, her grandmother who herself is a Priory of Sion member could explain it better than Langdon. There is no danger either to Sophie or Sophie's grandmother or to the holy grail. Silas could never get the holy grail with the information Jacques gave and it was just a red herring. If he wanted Sophie to find her family or her grandmother, all he had to do was do nothing. Her grandmother who knew about Sophie would find her anyway after things calmed down.

Teabing is utterly convinced that DNA testing of Mary Magdalene's body will prove that Sophie is her descendant (and by default a descendant of Jesus Christ). However, although human bones can last for thousands of years, DNA deteriorates, and without knowing how Mary Magdalene died or what state her body was buried in, it would be entirely possible that a valid sample could not be extracted from the body. An educated man who had devoted his life's work to the cause should have known that, and mentioned it in his explanations to Sophie and Langdon.

Since Sophie is repeatedly referred to as 'the LAST living descendant of Jesus Christ', her biological grandmother must therefore not be of the bloodline herself. So how did she find out about it? When Sophie's parents and brother were killed in the car crash, the cover-up story was that Sophie died in it too. We see Sauniere carrying Sophie away from the crash site, so how did her grandmother find out that Sophie was still alive? Surely, notifying an outsider (even her own grandmother) of both of Sophie's existence AND of her bloodline, would be a huge security risk and defeat the point of the elaborate cover story and Sauniere adopting her? It makes more sense that the grandmother (who was not in the car and therefore did not see that Sophie survived) would be told the same cover-up story as the newspapers were.

Spoilers

The goof items below may give away important plot points.

Character error

(at around 1h 5 mins) One of the key "facts" used to justify the alternative interpretation of the Holy Grail is that there are no cups or glasses on the table in 'Leonardo da Vinci''s Last Supper. In actual fact there is one immediately next to Jesus' left hand, which can be seen in high definition reproductions of the original.

Continuity

When Leigh Teabing is holding the gun to Sophie's head in Westminster Cathedral, the hammer is cocked. But when Sophie picks up the gun after Teabing drops it to try to catch the cryptex, the hammer is down (yet no shot was fired).

(at around 1h 55 mins) When the cryptex hits the floor and the vinegar vial breaks, it sprays some of its content and keeps rolling and is then manipulated by Teabing. After Teabing is being arrested you see a close-up of the cryptex on the floor and it's lying in a very large pool of vinegar - too much content for the little vial and too much regarding the fact that some of it has already been spilled.

(at around 1h 45 mins) Right after Silas turns and shoots at Aringarosa he goes up to him. The pistol's slide is open (gun empty)/closed (gun loaded) between shots. Then when he turns to the police, the slide is closed again.

Crew or equipment visible

(at around 2h 15 mins) In the final sequence of the movie, when Langdon is on the top of Louvre's inverted glass pyramid, the traveling movement of the camera operator and his assistant are seen by the glass reflection.

Incorrectly regarded as goofs

(at around 1h 50 mins) Aringarosa is shot by Silas on a lane way which has a gradient. A camera angle shows an aerial view of the body. A pool of blood appears to surround the upper body and an area above his head. This could only happen if it could flow uphill. However, as is clear from earlier close-ups, this is not a pool of blood but his cape.

Plot holes

Neveu is said to be the *only* living descendant from Christ and the Merovingian Royal Family. However, 'Prince Charles', Juan Carlos de Borbón, Kronprinsessan Victoria and virtually all other living royal family members of Europe, are almost certainly descendants of of the Merovingians, and therefore according to the movie, descendants of Christ.

The film suggests that Sophie Neveu is descended from Christ and that this can be proven by comparing her DNA to that of the body of Mary Magdalene. Even if this were done and a DNA match confirmed it would only prove she was related to Mary Magdalene not Christ.

When Robert and Sophie go to the Roslin church and go down to the lower chamber, Mary's Sarcophagus was supposed to have been there at one time, yet it would have been impossible to get the huge Sarcophagus down there through the narrow passage, unless the church was built around it. If that is true, then how was the Sarcophagus removed from the cellar of the church?

As the group are driving away from the airfield - after fooling the just-arrived English police - there's a cut to Aringarosa receiving a phone call from "The Teacher" about an exchange location for the 20m Euros he's asked for. We then cut back to the group just as the car stops and they get out - how did Teabing manage to call Aringarosa and have such an incriminating conversation with Sopie and Robert sitting right next to him? He does have an accomplice in the ruse, Remy, but he's also in the car - and since Teabing kills Remy to preserve the secrecy of his identity it doesn't seem likely that he has any other accomplices.

We can also conclude that it can't be an ill-executed time jump, since we know the group is in a rush after the airfield, and the timing of bringing Silas and Aringarosa to the safe house at that particular time appears to be part of the plan (to tie up loose ends and distract the police while Teabing extorts the solution from Sophie).

This is a hole in the Book and Movie. The whole story revolves around Jacques Saunière, the museum's curator passing on the secret of the Grail. He does this by sending His Granddaughter and Robert Langdon on a treasure hunt all over Europe, The end of the hunt leads to Scotland and His wife, Who confirms the secret. This could have done by telling His granddaughter to go see her granny in Scotland, saving her and us two hours of pointless wandering around Europe.

CORRECTION: Sophie's grandmother is not Sauniere's wife. Sauniere was not related to Sophie. He adopted her and told her he was her grandfather but, as Robert Langdon states, he was not. Sophie's grandmother states that she gave Sophie up, not knowing if she would ever see her again. Sauniere sternly informs Sophie that she must never, ever, go looking for information about her family again. The viewer is told that this is because any connection to her birth family would put Sophie in mortal danger. Therefore, it is unlikely that Sauniere knew or kept a record of the whereabouts of Sophie's grandmother, let alone direct contact details. He could not tell Sophie to go looking for the Priory of Scion at the Rosslyn Chapel in Scotland, directly, because he knew that that would alert those who would harm Sophie for what she was, and put her in direct danger.
